A bonus complementarity in Simplified Models of Dark Matter

Abstract

Nowadays there is an active discussion about the definition of Simplified Models of Dark Matter (SMDM) as a tool for interpreting LHC searches. Here we point out an additional simplified set-up which captures a very well motivated mechanism beyond the Standard Model: the kinetic-mixing of an extra U'(1) gauge symmetry. In addition to that, even if most of the attention has being paid on LHC "mono-signals", here we highlight an unavoidable signature appearing in SMDM with s-channel mediators: dijets or dileptons with no missing energy. We translate these searches into lower bounds on the DM couplings to the visible sector, showing the nice complementarity with the previous analyses, such that the parameter space of DM is being reduced from above and from below.
